Compared with gold CIP process and other traditional gold extraction processes, Xinhai gold CIL process greatly shortens the cyaniding time, reduces the capital backlog in the gold retention stage. Taking the gold cyanidation plant with processing capacity of 100000 tons and gold grade of 7.5 g/t as an example, gold CIL process can save the investment cost of $486000 than the CIP process ...
Process of Cyanide Gold Extraction
Here I present an Process EXAMPLE of Gold Extraction Cyanide in which the cyanidation feed consists of a pyrite concentrate floated after the selective flotation of a copper-gold concentrate. The pyrite concentrate is reground to 90% minus 325 mesh and aerated in a high-lime solution prior to cyanidation. It contains 99% sulphides of which 10 to 20 percent is pyrrhotite and 0.3 to 0.7% ...
Ultrasound-assisted cyanide extraction of gold …
In general, at the optimal gold extraction pH of 10.5 or higher, most of the cyanide is presented in the CN −, where cyanide loss by volatilization of hydrogen cyanide acid (HCN) is limited effectively. Ultrasonic cavitation can accelerate certain physical and stone reactions and may even trigger new reactions. Therefore, the effect of ultrasonic treatment on the loss of CN

Cyanide Leaching Chemistry & Gold Cyanidation
The reactions that take place during the dissolution of gold in cyanide solutions under normal conditions have been fairly definitely established. Most agree that the overall cyanide equation for leaching and cyanidation of gold is as follows: 4 Au + 8 NaCN + O2 + 2 H20 = 4 NaAu(CN)2 + 4 NaOH. Cyanide Leaching Chemistry. In a relatively simple system of this type the gold dissolves readily ...
